' I'Claim. (C1. 240- 101 This invention relates to certain new and useful improvements in display lighting fixtures.

The invention has fora principal object the provision of a lighting fixture of the construction hereinafter more fully set forth especially designed and intended to best) positioned with respect to a display of articles such as novelty jewelry or the like for directing light beams upon such articles as to cause the same to sparkle brilliantly, with a resultant greater appeal to the eye of the potential or prospective purchaser. r

Another and equally important object of the invention is to provide in such fixture a means for rotating the light producing elements to thereby increase the sparkling effect of the articles upon which the light ays are moved across.

Yet another and equally important object of this invention is the provision of such a lighting fixture which may be either suspended from a point above the articles upon which the light is directed, or supported from a suitable standard or pedestal;

Another object of the invention resides in the simplicity of construction. 7 7

Other objects will appear hereinafter.

The invention consists in the novel'i'combination and arrangement of parts to be hereinafter described and claimed. a

The invention'will be best understood by reference to the accompanying drawings showing the preferred forin of construction, and in which:

Fig. 1 is a perspective view of the preferred form of construction of the invention;

Fig. 2 is a rear view of the same;

Fig. 3 is a side view of the same;

Fig. 4 is a perspective view of the arrangement for suspending the fixture from a point above the articles to be illuminated;

Fig. 5 is a vertical sectional detail view taken substantially on line 55 of Fig. 1;

Fig. 6 is a sectional detail view taken substantially on line 6- 6 of Fig. 5;

Fig. 7 is a fragmentary detail view taken substantially on line 77 of Fig. 5;

Fig. 8 is an exploded view of a contact carrying structure embodied in the invention;

Fig. 9 is a sectional detail View taken substantially on line 99 of Fig. 7;

Fig. 10 is a fragmentary sectional detail view taken substantially on line 10-10 of Fig. 3.

The several objects of the invention are accomplished by the preferred form of construction shown in the accompanying drawings.

In this connection 10 indicates a base plate to which is attached a post or standard 11 extending upwardly therefrom. Carried by the post 11 is a U-shaped yoke 12 comprising arms 13. Formed in each of the arms 13 is an opening 14 through which a thread-bearing shank 15 a hand Wheel- 16 having a boss 17. The shank 15 is adapted to be threaded into an opening 18 formed in a spacing block 19 secured to an adjacent wall 20 of a casing 21. Disposed between the block 19 and the arm'13 and between the arm 13 and the boss 17, are washers 22.

By adjustingthe hand wheel 16 in a clockwise direction; the arm13 will be securely bound between the washers 22 and thereby secure the casing 21 in any one of a number of positions with respect to the yoke 12, as shown for instance'in full lines and dotted linesin Fig. 3, thereby to direct light rays at any desired angle upon the disprojects. The shank 15 is formed as an integral part of played article's.

If'it'be desirable to suspend the casing 21 from a position above the articles upon which light rays are to be directed, this'may be accomplished by removing the base 10 and threading upon the post 11 thereof a nipple 23 having an eyelet 24 to receive an open hook 25 threaded into an overhead support 26.

When thecasing 21 is supported from an overhead 'sus pension as shown in Fig. 4, it may be adjusted in any desired posit-ion 'with respect to the yoke 12 for reasons hereinbefo're stated with respect to Fig. 3.

The casing 21 includes an open front closed by a face plate 27 having a plurality of'openings 28 formed therein closed by electric light bulbs 29 of a well-known standard constfuctiomh'avinga threaded base 30 threaded into a socket 31 arranged in an enclosure 32 formed as a part of a housing 33 into which the electric bulb 28 'i'sarranged as shown in Fig. '5. Each socket31 by suitable conductor wires 34 is connected in an electric circuit iiicl'uding a'three-way switch 35 of any approved construction, the" switch havin suitable switch contacts (not shown) controlling the circuit through the conductor wires 34. The electric bulbs 29 preferably are connected in parallel with corresponding end portions of the conductor Wires 34 connected to conductor rings 36 mounted" upon an insulating plate 37 secured to a mounting block. 38 by means of studs 39. The block 38 is hollow inconstruction and is secured as at 40 to the face plate 27..

The faceplate 27 is rotatable in the open front of the,

casing 21. The mounting of such face plate 27 in said. opening fqr such rotation is accomplished by securing to ,the back wall 41 of the casing a spider bracket 42 having a bearing sleeve 43 formed integral therewith.

Extending through the sleeve 43 is a shaft 44, the end 45 of which projects through an opening 46 formed in the plate 27 and is adapted to have threaded thereon a hand nut 47. The hand nut 47 bears upon a split spring washer 47' removably fixed to the end of the shaft 45 whereby to retain the face plate 27 mounted upon the shaft 44 during removal of the hand nut 47 therefrom. Fixed to the shaft 44 is a bushing 48. Carried by the shaft 44 in spaced relation to the bushing 48 is a coupler pin 49 (Figs.

5 and 7), the ends of which are adapted to engage in slots 50 (Figs. 5 and 6) of a hub 51 fixed to and carried by the insulating plate 37.

Thearrangement is such that by removing the hand nut 47 from the threaded end portion of the shaft 44, the plate 37 may be moved outwardly from the casing 21 longitudinally of the shaft 44 to disengage the hub 51 from the ends of the pin 49. When the face plate 27 is mounted in the position shown in Figs. 1 and 5, the hand nut 47 securely connects the face plate to the shaft 45 for rotation therewith. The rotation of the shaft 44 and consequently the rotation of the face plate 27 and the light bulbs carried thereby, is accomplished by fixedly mounting on the shaft 44 a gear 52. This gear 52 (Figs. 5 and 7) meshes with a pinion 53 mounted on a shaft 54. Mounted on the shaft 54 is a gear 55 which meshes with a worm gear 56 mounted on the armature shaft 57 of a motor 58 supported within the casing 21 upon the sleeve 43 as best seen in Fig. 5. The motor may be of V to such form.

any standard construction which will best serve the purpose.

The motor is connected in an electric circuit including the three-way switch 35 which has suitable switch contacts controlling the circuit of the motor 58. Current to the contact rings 36 is supplied through contact pins 59 which are connected in the circuit of the electric lights. These contact pins 59 are movably carried in slots 60 formed in a block 61 fixed to a bracket 62 in turn fixed as at 63 to the rear wall 41 of the casing 21. The contact pins 59 are yieldably urged into bearing engagement with the rings '36 by expansion springs 64 (Fig. 8). For the purpose of ventilation, there is formed, in the rear wall 41 of the casing 21 a plurality of openings 65 of which there may be any desirable number and size.

The switch 35 may be operated by a pull chain 34' .(Fig. 3). The first operation of the pull chain energizes the motor 58 resulting in rotation of the face plate 27. The second operation of the pull chain results in energization of the electric bulbs, and the third operation of the pull chain simultaneously deenergizes the motor and the electric bulb circuit. In practical use, it is found desirable that the outer face lighting fixture may be suspended either from a position above the articles upon which the light rays are to be directed, or may be supported by means of the standard -or pedestal positioned upon the floor or the like, and that the casing may be supported in various angled positions for the most eifective result.

The rotation of the electric bulb carrier which includes the face plate 27, will bring out the maximum sparkling effect of the articles and, with the employment of different colored electric bulbs, the various colors will be blended during rotation of the face plate.

The display lighting fixture embodying my invention may be constructed at an economical cost and will be highly eflicient in use for its intended purpose.

The form and design of the casing as shown in the drawing is a preferred form and I do not-desired to be limited While I have illustrated and described the preferred form of construction for carrying my invention into efiect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim." 7

Having thus described my invention, what I claim as new and desire to protect ,by Letters Patent is:

A display lighting fixture comprising a circular casing adjustable about a horizontal axis, said casing having an open front, a removable electric light bulb carrier rotatably mounted within and closing said open front of said casing, said carrier having a plurality of openings formed therein, a housing having an electric socket carried by said carrier inwardly of eachof said-openings, electric bulbs threaded into said sockets so as to be fixedly connected to said carrier with their faces extending exterior of said openings, means for rotatably mounting said car,- rier about a center axis of said circular casing, said rotatably mounting means including a motor driven gear shaft extending co-axially of the center axis of said circular casing and said carrier and having intermediate its ends a coupling member for detachably rotatably connecting said carrier to said shaft, said carrier including a mounting block extending co-axially of and through which is freely journalled said shaft, said block providing a cooperating coupling member or rotatably connecting said carrier to said shaft within said casing, and spring urged contact pins of different lengths within said casing extendingin a spaced apart parallel direction with respect to said gear shaft and in end engagement with a stepped surface contact disc rotatably carried by said block adjacent the cooperating coupling member for maintaining an electric circuit for said bulbs during rotation of said carrier by said rotating means.
